Correction about Lamport timestamps: An observant student points out that there's an error in my notes. The system clock is set to (message timestamp + 1) if the receiver's clock ≤ message timestamp, not just if the receiver's clock < message timestamp. You never want two causally related events to have the same Lamport timestamp.
